Abstract:
Thirty patients underwent coaxial needle aspiration biopsies of lesions of the lung under CTG. Tissue obtained was adequate for diagnosis in 90 per cent of the patients. The incidence of pneumothorax was low using the coaxial needle technique. The limitations of the fine needle are diminished, and the risk of tumor implant during the procedure is greatly minimized. Additional studies should be conducted to further evaluate this technique and confirm its safety.

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
